I recently purchased a 90mm graflex lens in the original factory packaging with the matching cam. I have confirmed that they match and are correct...I am having trouble setting the infinity stops for this lens though. They don't seem to go back far enough.

Here's what I've done so far.....

I put my camera on a tripod...

I set my focus scale so that the two infinity marks match up (for my 135mm lens).

I unlocked the front standard and slid it forward and back until I had an object at least a couple blocks away in focus.

I locked the front standard at that set point.

I found that the infinity stops wouldn't go far enough back to make this spot on the rails the infinity stop. The front standard is just behind the front door hinge when it says it's in focus via the ground glass.

I have the cam for this lens...it's a 90mm in the original Graflex box....so I don't know what I'm doing wrong hah!
